I am a US resident
I was making iphone app by myself from 2011 till 2012, and I don't make any money… I am living with family in Hong Kong. I don't drive, and I live with parents, so i don't need to pay rent, utility, gas, etc…
I was only using my saving little by little…
so do I need to file tax return for 2011 and 2012?
If I need to, do I just put a zero on form 1040?
Please advise
